dxDrawText Error Help!

[MatreN]

local sX, sY = guiGetScreenSize()

local customFonts = dxCreateFont("Roboto-Light.ttf", 82, true)

local scale = {(sX/1920) * (sY/1080)}/2

local R, G, B = 255, 255, 255

function drawRects()
        --dxDrawRectangle(0, 0, sX*0.104, sY*0.185, tocolor(R, G, B))
        --dxDrawRectangle(sX*0.104, 0, sX*0.104, sY*0.185, tocolor(0, 255, 0))

        
        dxDrawText("Hello There!", 0, 0, sX, sY, tocolor(R, G, B) , scale*0.5, customFonts "right", "bottom")


end 
addEventHandler("onClientRender", root, drawRects)

function changeColor(_, r, g, b)
        R, G, B = r, g, b
end 
addCommandHandler("rekt", changeColor)

I want to print a text on the screen, but I get this error.

 

ERROR : dxDrawText/text.Lua:5: attempt to perform arithmetic on a table value

[MIKI785]

local scale = {(sX/1920) * (sY/1080)}/2

You're making a table here, isn't it supposed to be regular brackets here?

local scale = ((sX/1920) * (sY/1080))/2

I am not aware, I have to be careful with this.

Also don't forget to convert strings to numbers, when typing the command. (+ fallback)

R, G, B = tonumber(r) or 255, tonumber(g) or 255, tonumber(b) or 255
